Newmark's Direct Integration Method

Integrate a 1-DOF system using Newmark's Direct Integration Method.

Description

Integrate a 1-DOF system using Newmark's Direct Integration Method. Calculate the system response for an externally applied load and variable system parameters. Even let's you change the integration method by altering Newmark's Coefficients. Uses in: Structural Engineering.

NOTE: if you have an accelerogram for input, you must use p(t) = -m*a(t)

• MATLAB release: MATLAB 5.2 (R10)

Dear Jose Antonio Abell Mena,
I download your Newmark Direct Integration file. I want to use that but how can i do that, i don't know? I have acceleration-time history. And i want displacement and velocity graphs. I'm new on matlab. Please help me. Thanks

Works well, thanks for sharing this! Also great that it contains enough comments to be understandable for others.

One little error is present in the file:
Line 56: 'u2dot = u;' contains a typo, therefore the u2dot isn't pre-allocated.
